Kris Jenner says Kourtney Kardashian has tried to fire her '3 or 4' times a day

• Kris Jenner said that Kourtney Kardashian has tried to fire her a few times.
• Kim Kardashian also tried to fire her in the first season of "Keeping Up With The Kardashians."
• Jenner said it's "the healthiest" for her not to think about Kim going through with firing her.

Kris Jenner said that Kourtney Kardashian has tried to fire Kris as her "momager" multiple times a day.

Jenner made that reveal during a conversation with WSJ Magazine editor-in-chief Kristina O'Neill, when O'Neill brought up an episode from the first season of "Keeping Up With The Kardashians" when Kim Kardashian tried to fire Jenner from her position as Kim's manager.

"Has anyone tried to quit you since?" O'Neill asked.

"No. I mean, Kourtney probably three or four times and that's just a day. A day," Jenner responded.

Kim said she wanted a 'more professional' manager in an early 'KUWTK' episode

In a scene from season 1 of "KUWTK," Kim said that while no one would probably look after her and her career like Jenner, she wanted someone "with a whole staff of people." She had Khloé Kardashian convey the news to Jenner, who did not take it well.

Ultimately, the mother-daughter duo did continue their professional relationship, and Jenner remains Kim's manager to this day.

Speaking about the experience, Jenner said that it's probably "the healthiest" for her to not think about Kim going through with firing her.

"I just always saw myself as somebody that she wanted in her life and needed in her life - as her mom and as her manager," Jenner told O'Neill during their chat.

"It was just a really exciting time for me to be a part of that whole new beginning for us. So I would have been devastated," she added.

Jenner has been a 'momager' to her famous kids for at least 14 years

"Momager" has become a well-known term for parents who also act as their kids' career managers, with the success of Jenner, the Kardashian family, and "KUWTK."

Since the reality show first debuted in 2007, several of Jenner's children have branched out and started their own businesses - with at least one of them (Kim) gaining a billion-dollar net worth in the process.

Jenner told O'Neill that she's "never met anyone busier than Kim," who was inducted into the three-comma net worth club in April.

"I look at her schedule several times a day. I get a fresh one every night and a fresh one in the morning," Jenner said. "And every single time she's got two or three hours blocked out in the afternoon, before her kids finish school, for her studying for law school."

Jenner also shared the unique way in which she brainstorms business ideas with Kylie Jenner, who has a successful skincare and cosmetics business.

"I went on a long walk with Kylie a couple of days ago," Jenner said. "And I think by the time we were done, we came up with three new business ideas."
